Abstract:
An aircraft engine attachment assembly having a wing section, an engine pylon, upper secondary attachment links, lateral load attachment links, and a number of fuse pins. The engine pylon is mounted to the front end of the wing section so that the engine pylon is not restricted by a minimum structural depth. The wing section, engine pylon, upper secondary attachment links, and lateral load links form primary and secondary attachment joints configured to form alternate load paths if one of the joints fails. The wing section and engine pylon include knuckle-off geometries for promoting mechanical fusing of the fuse pins during high energy dynamic events.
